Arken ABL-30 Bubble Level - 30mm Anti-Cant Device

The Arken ABL-30 Bubble Level is a lightweight anti-cant device designed to mount directly onto a 30mm riflescope tube. Canting the rifle - even by just a few degrees - can throw long-range shots off target, and a visible bubble level gives the shooter a quick, at-a-glance confirmation that the action and optic are perfectly plumb before the trigger breaks.

Installation is straightforward: the ABL-30 clamps to the scope's 30mm main tube and sits alongside the turret housing so the bubble vial is visible from the shooter's normal firing position. Once mounted, the level helps eliminate error from a canted rifle at the range or in the field, making it a practical accessory for precision and long-range shooters running any Arken optic (or any third-party 30mm tube scope).

Built as part of the Arken ABL series, this 30mm version is intended for Arken's 30mm-tube scopes such as the EPL-4, and pairs naturally with the Arken HALO Ti and ARP scope rings and cantilever mounts already on your rifle.
